Then, when many evils and troubles will have come upon them, this song will serve as a witness against them, since their descendants won't fail to sing it. I know the plan that they are devising even before I bring them into the land that I promised them by an oath."

David knew that Saul was devising evil plans against him, and so he told Abiathar the priest, "Bring the ephod."
